Description

3—ZOOM
4—FOCUS
5—IRIS
0 (lowest) to 255 (highest) or 0% to 100%
On pan, tilt, and PWM drives for zoom, focus, and iris, level 128 will be OFF. Level 129 and above are for the forward direction.
Level 127 and below are for the reverse direction.
If specified, 0 to 255 in tenths of a seconds; if not specified, at current rate.
0 to 255; value of POT input. Corresponds to a position of the unit. 0 is one end of the POT and 255 is the other end. Not directly related to an output level voltage.
0 to 65535 when using the 'AD MODE x 10' command, or for pan/ tilt commands. Corresponds to a position of the unit. 0 is one end of the POT and 65,535 is the other end. Not directly related to an output level voltage.
0 to 127; where 0 is slowest and 127 is fastest (default).

Deviation

Ramp Time
Description
0 to 127; where 0 is most accurate but can have some jitter.
Default is 2, which means the position can be within +/- 2 from the specified position.
0 to 127; distance from the specified position.
1 to 255; time in 10ms increments that it takes the motor drives to ramp up to speed.
The following table lists parameters for the PosiTrack Camera Controllers Positional Commands.
Positional Commands
GAS
Sets the output to slow down within the specified distance of the specified position for future 'GxLxxx' commands.
This command can be used for motor mode and servomotor speed modes.
Syntax:
"’G<output>A<distance>S<speed>’"
Variables (See Parameters - Send_Commands section on page 36):
G - output = 1 - 4
A - distance = 0 - 127
S - speed = 0 - 127
Example:
SEND_COMMAND CAM,"’G1A5S20’"
Sets PAN to speed 20 when within 5 of the specified position for future 'GxLxxx' commands.
GD
Sets the current maximum position deviation for future position
('GxLxxx') commands.
GL
Turns on the specified output at the current speed until the specified position (as read by the Pan or Tilt encoder) is reached.
This command can be used for motor mode and servomotor speed/positional modes.
Syntax:
"’G<output>D<deviation>’"
Variables (See Parameters - Send_Commands section on page 36):
G - output = 1 - 4
D - deviation = 0 - 127
Example:
SEND_COMMAND CAM,"’G1D4’"
Sets PAN deviation to 4 for future 'G1Lxxx' commands. Output will stop when it is within 4 of the specified position.
This command can be used for motor mode and servomotor speed modes.
Syntax:
"’G<output>L<position>’"
Command forces output to go to a preset position using the POT input as a reference.
Variables (See Parameters - Send_Commands section on page 36):
G - output = 1 - 2
L - position = 0 - 65535
Example:
SEND_COMMAND CAM,"’G1L32000’"
Sets PAN to search for position 32000 as referenced by the Pan or Tilt encoder.

Positional Commands (Cont.)
GL
Turns on the specified output at the current speed until the specified position as read by the POT input is reached.
This command can be used for motor mode and servomotor speed modes.
Syntax:
"’G<output>L<position>’"
Command forces output to go to a preset position using the POT input as a reference. (Positions 0-65,535 are available using the 'AD MODE x 10' command.)
Variables (See Parameters - Send_Commands section on page 36):
G - output = 3 - 4
L - position = 0 - 255 or 0 - 65535
Example:
SEND_COMMAND CAM,"’G3L100’"
GS
Sets the current speed for future and current
Send_Commands and channel commands.
Sets ZOOM to search for position 100 as referenced by the ZOOM POT input.
This command is used for motor mode and servomotor speed mode applications.
Syntax:
"’G<output>S<speed>’"
Variables (See Parameters - Send_Commands section on page 36):
G - output = 1 - 5
S - speed = 0 - 127
Example:
SEND_COMMAND CAM, "’G1S64’"
Sets PAN to speed 64 (50%) for current and future commands.
The G1 and G2 commands are used for all modes. The G3, G4, and G5 commands are for the Motor mode ONLY.
PLT
Ramps specified output voltage from current level to a specified level or percentage at the current rate or optionally in a specified amount of time.
This command can be used only for servomotor positional mode applications.
Syntax:
"’ P<output>L<level >[T<time >] ’"
Variables (See Parameters - Send_Commands section on page 36):
P - output = 3 - 5
L - level = 0 - 255 or 1 - 100%
T - time = 0 - 255 (in tenths of a second)
Example:
SEND_COMMAND CAM,"’P3L50%’"
Ramps zoom output to 50% (mid-voltage) at current rate.
SEND_COMMAND CAM,"’P4L255T30’"
Ramps FOCUS output to 255 in 3 seconds.
